Re: pthread_setname_np API is bad



I think we should stop playing games and provide a completely compatible api.
If we want enhanced API's, those should be provided as extra. Yes, the magic
printf(fmt, ...) works most of the time. How about the case where there is no warning?
Like "%%" which will print 1 % on NetBSD and 2 everywhere else? What are you
going to do then?
